2. A small business sells each CD of its game software for $12. How many CDs must they sell to meet the goal of at least $84,000? Solving Inequalities by Multiplying or Dividing COURSE 3 LESSON 2-7 Let c = the number of CDs. Inequality c 12 84,000 > – Wordsnumber of CDs $12 is at least $84,000 > – 12c 84,000 Divide each side by 12. 12c 12 > – 84,000 12 Simplify. c 7,000 > – 2-7

3. (continued) Solving Inequalities by Multiplying or Dividing COURSE 3 LESSON 2-7 The business must sell at least 7,000 CDs. Check for Reasonableness The answer makes sense because 7,000 12 is 84,000, and any number over 7,000 multiplied by 12 is a number greater than 84,000. 2-7
